Indeed haukex, I agree that validation for a filehandle would be good if it was a trivial thing to do. I couldn't have told you whether it was or wasn't off the top of my head, so thanks for the link.

The possible re-use of the scalar $first_fh did occur to me, but that's why I initially figured a warning might have been appropriate since someone could explicitly ignore that warning if they decided to re-use the variable name. I sort of leaned toward the, "well wouldn't that be kind of sloppy to re-use it anyway?" argument when it occurred to me, but I wouldn't be surprised if there were cases where it made good sense to do so.

Again, I did just really want the "filehandle used after closing" warning, though I can easily accept the answer that it's impractical.

Just another Perl hooker - will code for food
